Somehow I didn't receive Steve's response.  Anyway, I'm referring to apps that 
don't specify which port to use as the one's that don't care, versus those that 
do want to know their port.

In reality, the port space for RDMA connections over IB is distinct from the TCP 
port space.  No attempt is made to coordinate between the two, and I am not 
convinced that those two port spaces should be one and the same.  This is where 
I believe there's disconnect.
